Porsche Torque Vectoring (PTV) and
Porsche Torque Vectoring Plus (PTV Plus).
PTV (with manual transmission) or PTV Plus
(with PDK) is available as standardin
the S models and as an option for the
911 Carrera 4 models and the911 Targa 4.
Both systems actively enhance vehicle
dynamics and stability. Operating in
conjunction with a rear differential lock,
they work by intelligently braking the
rearwheels as the situation demands.
When the car is driven assertively
intoacorner, moderate brake pressure
isapplied to the inside rear wheel.
Consequently, a greater amount of drive
force is distributed to the outside rear
wheel, inducing an additional rotational
pulse (yaw movement) around the
vehicle’s vertical axis. This results in
adirect and sporty steering action
fromthe turn-in point.
With PTV, the rear differential lock is
regulated mechanically, while PTV Plus is
equipped with electronic control offering
fully variable torque distribution. In
interaction withPorsche Stability
Management (PSM), the system improves
driving stability not least on road surfaces
with varying grip as well as in the wet
and snow.
For the driver, this means strong
resistance to destabilising side forces,
outstanding traction and great agility at
every speed – with precise turn-in and
well-balanced load transfer characteristics.
What else? Tremendous fun in the corners.
